Say, Ms Mitya, I am wondering:
What exactly is the difference between a viola and a violin?
I hope you don't mind my stupid asking, but I don't know how to tell them apart, or what defines each one.
And I assmuse they sound differently too?

Intervals (fourths, fifths, etc.) are basically the number of notes between the top note and the bottom note. Those are included.
C to E would be a third. A major third, in fact. Half steps have a lot to do with it, but you didn't ask about it.

Leesi--Fourths are an interval of four notes from bottom to top, and fifths have five notes. And so on. A fourth would be A to D, and a fifth would be A to E, for example. I'll tell you more about this when you start your viola lessons.

Actually, my license plate really does say "DSCH-J".
The reason for the J is that there was already another car in Virginia with a license plate that just said DSCH (!), so my dad (who got me the vanity plates) stuck the J in there, for the first letter of my name.

Why wait for one? Make your own with your very own make-your-own bumpersticker kit.
all you need is a piece of posterboard or paper or something, and that heavy duty clear tape and a permanant marker, and a catchy phrase.
